basically non N*B. I made it. lol at you OB saying no one could ever make it. Let's not blame it on LA/Ranger not playing, cos I was gaining ground on them anyway. Had the scores been redone earlier, I would've already been here :)

6/20 -> 6 BA every 20 minutes
It's the highest tier in BA recharge rates (and increased rewards per BA spent), with the added advantage of absolutely no challenge bonus penalties of attacking anybody lower in score (you are guaranteed at least 0% CB no matter how small the target).
